In this video I go talk about the Image Aspekt Ratio and how to change it. Again my example was from OM-D E-M1 MkII, but in this blog post you can find how to change it in your Olympus.
In the following Olympus cameras the Image Aspekt Ratio is changed in
Shooting Menu 1:
E-M1, E-M1 MkII, E-M5, E-M5 MkII, E-M10, E-M10 MkII, Pen-F and Pen E-PL8
In E-M10 MkIII and Pen E-PL9 press the OK-button and then you can find the Image Aspekt on the side. (image: Pen E-PL9 manual, Olympus)
